Hello ,

First of all , hanks for this useful project .

But I have question , how to get device token from inside the spring boot back end, lets say I need to send a private message to user ,when I use web socket I use the other user name or login field, and spring boot will handle the rest of it.

As example :
messagingTemplate.convertAndSendToUser("userName", "/queue/xxx", activityDTO);
using this method spring boot handle the delivery of web socket message internally with no need to add any code.

Is there any kind of integration between spring boot and fire base in that way , or I have to implement some kind of code handling ,which mean when device authenticate I should send the fire base device token in http header and save it in a database , then when I need to send message to a device ,then get the related fire base token from database and use it to send push message.

Thanks for your valuable contribution

thanks alot for the example it is really very helpful meanwhile i faced the below error while calling sendAndGetResponse()

Can you make a tutorial about it .
@imaginalis please

Hi Imaginalis ,

Went through you blog very nicely explained. I also downloaded this project I am getting this error in response:
"FirebaseApp with name [DEFAULT] doesn't exist:
Have also added .json file in google/ folder.

I ran this on my local server. Can you point out what I am missing ?
I also noticed this issue mentioned on your blog: https://blog.mestwin.net/ but couldn't find an answer in the thread.

Thanks
Akshay
